First of all, I want to thank everyone who offered advice on my charging, or lack of charging, question from 12-06-09.

It turned out that the stator was the culprit. When I got the old one out, which appeared to be the original, it had several burnt windings. In addition, the coating covering the windings had become brittle and was flaking off. A new stator, bought from HelixParts.com for $109, seems to have solved my problem.
